Red eyes is a term commonly used to describe the redness or bloodshot appearance of the whites of the eyes. It is usually caused by dilated blood vessels in the eye, which can result from various factors such as fatigue, dry eyes, eye strain, allergies, or eye infections.
In some cases, red eye can be a symptom of a more severe condition, such as conjunctivitis, iritis, or uveitis. If the redness is accompanied by other symptoms, such as pain, vision changes, or discharge, it is vital to seek medical attention.

- Eye strain or fatigue: Prolonged use of computers or other digital devices can lead to eye fatigue and cause redness.
- Dry eyes: Not enough tears can cause the eyes to become dry, irritated, and red.
- Allergies: Allergic reactions can cause red, itchy, and watery eyes.
- Conjunctivitis (pink eye): This is an infection of the clear membrane that covers the eyes’ whites and the eyelids’ inside.
- Irritants: Exposure to smoke, wind or other irritants can cause the eyes to become red and irritated.

In some cases, red eye can signify a more serious condition and requires medical attention. If you are experiencing persistent or severe redness, it is crucial to seek medical advice.
